Krýsuvík is one of Iceland’s most dramatic geothermal areas, located on the Reykjanes Peninsula in southwest Iceland. Known for its steaming fumaroles, bubbling mud pools, and vividly colored mineral-rich hills, Krýsuvík offers visitors an unforgettable encounter with Iceland’s raw geothermal energy. Unlike glaciers and waterfalls that dominate many Icelandic landscapes, Krýsuvík reveals the intense heat and activity happening just beneath the Earth’s surface.
This geothermal field is a living reminder that Iceland is constantly being reshaped by volcanic forces. The smell of sulfur in the air, the sound of hissing steam, and the sight of boiling earth combine to create a sensory experience that feels almost otherworldly.
Krýsuvík is situated on the Reykjanes Peninsula , approximately 40 kilometers south of Reykjavik . The area lies along the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates are slowly pulling apart ..

The geothermal fields of Krýsuvík stretch across a wide area near Kleifarvatn Lake, making it easily accessible by road and a popular stop for travelers exploring southwest Iceland.
The name Krýsuvík is believed to derive from an old Icelandic female name or possibly from words describing the landscape. Historically, the area was inhabited and used for farming, though harsh conditions and geothermal activity eventually made permanent settlement difficult.
Throughout history, Krýsuvík has been known for its geothermal power and sulfur deposits. These natural resources were once considered valuable for industrial use, though large-scale mining never fully developed.
Krýsuvík is characterized by intense geothermal activity caused by magma close to the Earth’s surface. Underground water is heated to extreme temperatures, producing steam vents, fumaroles, hot springs, and boiling mud pools.
The soil in the area is highly acidic, preventing vegetation from growing and leaving the landscape bare and colorful. This constant geothermal activity ensures that the land is always changing.
Seltún is the most visited part of Krýsuvík and features well-maintained walking paths and viewing platforms. Here, visitors can safely observe bubbling mud pools, steaming vents, and mineral-stained hillsides.
The vibrant colors of yellow sulfur, red iron oxides, and white salts create a striking visual contrast against the dark volcanic earth.
The bubbling mud pools at Krýsuvík are among its most fascinating features. Thick, mineral-rich mud boils continuously, forming large bubbles that burst and reform in an endless cycle.
These mud pools are formed when geothermal steam rises through clay-rich soil, mixing with water and minerals to create a constantly moving surface.
Steam vents, also known as fumaroles, release superheated steam and volcanic gases into the air. The hissing sound of escaping steam is constant throughout the area.
The strong smell of sulfur is a defining characteristic of Krýsuvík and a clear sign of the volcanic gases rising from below.
Krýsuvík is famous for its vivid mineral colors. Sulfur creates bright yellow patches, iron-rich deposits produce deep reds and oranges, and white mineral salts coat the ground.
Rain and geothermal activity constantly alter the patterns and colors, ensuring that no two visits look exactly the same.
Krýsuvík is part of the Reykjanes volcanic system, one of Iceland’s most active regions. The peninsula has experienced increased volcanic activity in recent years, highlighting its geological significance.
Fissures, lava fields, and geothermal zones across Reykjanes demonstrate the ongoing movement of tectonic plates.
Due to extreme heat and unstable ground, visitors must remain on marked paths at all times. Thin crusts can cover boiling mud or steam vents, making off-trail walking dangerous.
Clear warning signs and walkways help ensure a safe experience while allowing close observation of geothermal features.
Krýsuvík can be visited year-round, but the best conditions are typically from May to September. Summer offers easier access, milder weather, and longer daylight hours.
Winter visits are also possible and visually striking, with steam rising through snow-covered terrain.
In winter, Krýsuvík becomes especially dramatic. Snow contrasts sharply with the colorful geothermal ground, and steam rises thickly into the cold air.
While winter visits require caution due to icy paths, they offer a unique and memorable perspective.
Krýsuvík is a favorite location for photographers due to its textures, colors, and constantly shifting steam. Overcast days often enhance the intensity of colors.
Protecting camera equipment from steam and sulfur residue is recommended.
Krýsuvík is frequently included in Iceland holiday packages focusing on the Reykjanes Peninsula and geothermal attractions. It is often combined with nearby sites such as Kleifarvatn Lake, Gunnuhver, and the Blue Lagoon.
Including Krýsuvík in an itinerary offers travelers insight into Iceland’s geothermal forces in an accessible setting.
Krýsuvík is a protected natural area. Visitors are encouraged to respect the fragile environment by staying on paths and following Leave No Trace principles.
Preserving this geothermal landscape ensures it remains safe and accessible for future generations.
Krýsuvík offers one of the most immersive geothermal experiences in Iceland. Unlike distant volcanoes or glaciers, the geothermal activity here is immediate and tangible.
It is a place where visitors can truly feel the power of the Earth beneath their feet.
